'Be it knownthat I, HENRY C. HERR, va

I 'citizen of theUniteda States of- America, re-

` and 2 is provided with a rotating Wheel B,

` ,rolls t work; and Fig. 10 is a viewsimilar to Fig.:

' sidin'at Detroit, in the county of Wayne.

and ate' of- Michigan, have 'invented certain 4"new a and useful Improvements 1n Machines for Forming Metal Hoops, of which the followingis a specification, referencebe ing had therein to 'the accompanying drawings.

The invention-relates to machines for forming metal hoops, and has for its ob-l 'ect the obtaining of a construction in which the hoop isboth fashionedjin cross. section and curvedlon'gitudinally. r l l on consists in the To this end, the inventi construction .as hereinafter set forth.

' In thedrawings-Figure v1 is4 a sectional elevation of the machine', Figi?. is a similar view' looking at right angles to `Figf': 1);"Figs. 3 to 9 are sections showinglthe forming -Which successively'operate upon the l, showing a modification. l

In the manufacture of luar'rels, and. parl ticularly barrels in vvhichfy he body portion `metallic; hoop'sj These hoops are so fashioned in cross'section as to perform thefunc tion of -croze and chime in the ordinary Wooden'ba'rrel, aswell as 4forming a reinforce for the paper body. It is therefore necessary in formingl the hoops to fashion the metall'to the proper sectiomffand also to bend *it longitudinally to the curve ofthe barrel body. vThese results are accomplished forming the section' ofthe hoop, and arranged insueh relation to' eachother that also curved longitudinally.,

` In detaihAis the frame of the machine, on Whic h "are mounted the forming rol1s',and which in the construction shown in Figs. 1

havingits peripheral portion r to. constitute a master die. The Wheel is ay gear portion D, Whih is driven by engagement with a pinion' E on a shaft F. This shaft in turn is driven through the' inter- .meshing gears G ,and H from a'drivepulley I A I sleeved upon Ia Shaftywupon which the the master gear WheelD.

is formed of paper, the hea s are secured by by amachine comprising 'a series of form-y ,1ng rolls for successively and progressively the metal vin passing through the series is C fashioned l also provided adjacent to the portion C With i Wheel Bis mounted.' i Around the peripheral 'portionv of the frame are arranged a series of shafts K, K', etc'., upon Which are mounted the fashioning rolls L, L', etc. The lat ter are arranged in peripheral engagement With the Vmaster die C and are radially ad justable in relation bysu-itable means, such as theladjusting screws M. Certain of the rolls, such as L, L', are positively driven at the same peripheral s eed as `the master wheel through the me iumof the pinions N, N adjacent'thereto which engage with The master die C is of the sameoross sec tion in all portions lof its periphery, but the cooperating,rolls L, L', etc., vary in form, and are designed to progressively affect the bending ofthe material into conformity.

with the master die.4 Furthermore, these rolls L, L., etc., in successivelyengaging with the hoop, Willrbend itlongitudinally around the'xnaster die at the same time thatit is being v'fashioned in section. The result is that at the completion of thecycle' the metal will be bent into. conformity to the section of the master dieV and into substantially the same curve, but the exact, diameter of the circle inwhich'the hoop is bent is depend* ent upon the adjustment of the rolls L L y y in relation to the mast-er die. Thus by suitable adjustment, any diameterwithin certain limits may be obtained.

Figs. 3 to 9, inclusive, shoveT the specific form of the successive rolls lfor forming the specific construction of hoop illustrated.

The master die -is provided with acylin drical portion a, the outwardlyextending V flange b at one end of the portion a, and at its oppositejend theinwardlyextending inclined portion 0,' and the' incllnedportions (l and e, the lattcr'portions forming upon the strip the croze for `receiving the head of the barrel-. The first of the series of rolls Ll has ths shoulder f cooperating With the Voutwardly-eirtending flange bron the master die tosta-rt the formation of a ange b; This same roll has a portion g which bears upon the'central portion of the hoop and as` sists in feeding the same. L completes the formation of the flange b and is provided with a flange h; to.hold the The second roll` opposite edge of the hoop in position.l The rrollrL2 has` 'an lo,utvvardiy-projecting V- shaped portion -z' for-starting the formation of portion c d' dinal bending of the strip. With this conioned to progressively form"`the Work, and

z comprisingy a. master `die vand a series of forming rolls ,coperating therewith to simultancously shape the face of the same contour or configuration throughout, and y bers having working faces each corresponding to but a `portion of the work surface andthe hoop and for l' What I claim as my invention-is:

' strip, and a series of formin l peripheral 'working faces, said master d1e of the hoop and these are completed by the roll L3, which also has a V-shaped portion j complementary to the V- shaped groove between the portions c dof the master die. The succeeding rolls L4 Ls Lb form the inclined portion c of the'hoop, and the ylast-mentioned roll has a portion cooperating with a portion m on the master die foi-,forming a slight return bend n in drawing the metal to remove 1all kinks or fullness therefrom.

It will be observed that the operations performed by the rolls above described gradually draw in the metal toward one sidev of the hoop, and at the same time in passing around the master die and -into engagement with the vsuccessive rolls the metalI is bent longitudinally to the required curve.

In the construction illust-rated in Fig. 10, in place of the large wheel constituting the master4 die, a series of small rollsP, P, etc., are arranged in a curved path, a part of said rolls being in proximity to andcoperating with the rolls L, L, etc., while the intermediate rolls P2, P3, etc., produce the longitustruetion, the rolls P, P', etc., may be fashthe final roll of the series is of the form of the fashioned strip. This construction is, however, more complexl than the constructiony first described, and ,I deem the latter-to be preferable.
